It totally annoys me as well when you see 'Stantead' rather then Stansted especially by so called aviation enthusiasts as well as the general media.
Another one that seriuosly annoys me and yes you can probably forgive most for spelling it as Stanstead but when you see 'Thompson' or even 'Flythompson' rather then just Thomson that gets my back up even more!
Sorry about the rant but after the last few posts I felt I needed to get it of my chest
